BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to all forms of footwear, including street andathletic, as well as any other products benefiting from increasedflexibility, better resistance to shock and shear forces, and morestable support. More particularly, the invention incorporates devices asa unitary integral insert or component with at least one internal (ormostly internal) sipe, including slits or channels or grooves and anyother shape, including geometrically regular or non-regular, such asanthropomorphic (or animal) shapes, into a large variety of productsincluding footwear using materials known in the art or their current orfuture equivalent, as well as materials that are very firm compared tothose taught in the art.

Still more particularly, the unitary internal sipe insert or componentprovides improved flexibility to products utilizing them, as well asimproved cushioning to absorb shock and/or shear forces, includingthrough the use of firm materials, while also improving stability ofsupport, and therefore the siped devices can be used in any existingproduct that provides or utilizes cushioning and stability. Theseproducts include human and other footwear, both soles and uppers, andorthotics; athletic, occupational and medical equipment and apparel;padding or cushioning, such as for equipment or tool handles andfurniture; balls; tires; and any other structural or support elements ina mechanical, architectural or any other device. Still moreparticularly, the integral insert or component with at least one sipe,including in the form of a slit, can include a media such as a lubricantor glue of any useful characteristic such as viscosity or any material,including a magnetorheological fluid.

The invention further relates to at least one chamber or compartment orbladder surrounded, partially or completely, by at least one internal(or mostly internal) sipe, including at least partially in the form of aslit, for use in any footwear soles or uppers, or orthotic soles oruppers, including the use of firm materials, and for other flexibility,cushioning, and support uses in athletic equipment like helmets andapparel including protective padding and guards, as well as medicalprotective equipment and apparel, and other uses, such as protectiveflooring, improved furniture cushioning, balls and tires for wheels, andmany other uses.

The internal sipe integral insert or component invention further can beusefully combined with the applicant's prior footwear inventionsdescribed in this application and expressly incorporated by referenceherein below, including removable midsole structures and orthotics andchambers with controlled variable pressure, including control bycomputer, for example.

2. Brief Description of the Prior Art

Existing devices are generally much less flexible than would be optimal,especially products for human (or animal or other biological-based)users, whose non-skeletal anatomical structures like bare foot solesgenerally remain flexible even when made hard by significant pressurecaused by body weight, whereas the products interfacing directly withthem are often much more rigid.

Taking footwear soles as one example, cushioning elements like gasbladders or chambers or compartments are typically fixed directly inother midsole foam plastic material to form a structure that is muchmore rigid than the sole of the human wearer's bare foot, which isrelatively soft when unloaded and hard but still flexible when loadedunder body weight. As a result, the support and cushioning of the barefoot are seriously degraded when shod in existing footwear, since therelatively rigid shoe sole drastically alters by obstructing the way inwhich the bare foot would otherwise interact with the ground underneatha wearer. The effective natural interface is replaced by an inferiorartificial one.

The use of open or external traction sipes—that is, sipes in the form ofslits or channels that typically are substantially vertical and open toan outside surface, particularly a ground-contracting surface—to providealso flexibility in footwear soles has been fully described by theapplicant in prior applications, including the examples shown in FIGS.55A-55C, 56, 57, and 73A-73D of both the applicant's prior footwear U.S.patent application Ser. No. 11/190,087, published as Pub. No.2005/0268487 A1 on Dec. 8, 2005, and the applicant's prior orthotic U.S.Pat. No. 7,010,869, issued Mar. 14, 2006, (as well as continuation U.S.application Ser. No. 11/108,034, published as Pub. No. 2005/0217142 A1on Oct. 6, 2005), and in FIGS. 35-40 of U.S. patent application Ser. No.11/179,887, published as Pub. No. US2005/0241183 on Nov. 3, 2005, all ofwhich foregoing U.S. patents and published applications are hereinincorporated by reference for completeness of disclosure.

The applicant first described such non-traction oriented open externalsipes in footwear in PCT Application PCT/US90/06028 titled “Shoe SoleStructures Which Are Siped to Provide Natural Deformation Parallelingthe Foot” filed 19 Oct. 1990 and published by WIPO as Int. Pub. No. WO91/05491 on 2 May 1991. Such open external sipes principally provideflexibility to the footwear sole by providing the capability of theopposing surfaces of the sipe to separate easily from each other.However, external sipes are structurally unlike natural anatomicalstructures (since to be effective, they must be much deeper than surfaceskin texture like finger prints, the closest anatomical analogy).

Also, external sipes tend to introduce significant instability bycreating excessive edge weakness in the shoe sole adjacent the sipes,just like a paperback book being unable to support weight when standingon end with the pages vertical, but stable when the book and pages arelying flat. External sipes by being open also collect debris in thesipes, seriously reducing sipe performance. In addition, the mostoptimal pattern and depth of such sipes is unknown and thereforedifficult to ascertain directly, except as an error-prone trial anderror process guided by second-guessing nature, since deep, open sipesare obviously not used in the design of the human foot. Moreover, theonly way to get relatively seamless, continuous natural flexibility likethe human foot sole using external sipes is to introduce a very largenumber of deep sipes on as many different axis as possible in the shoesole, which produces an impractically soft and unstable shoe sole, theuse of which would be roughly like trying to stand on the edge of alarge urban area telephone book.

Instead, a much more reasonable and fool-proof procedure is to follow asclosely as practical the natural design of the human anatomical footsole structure with which it is intended to interface to create theclosest-to-natural flexibility.

The use of a integral component with internal sipes in footwear soleslike those described in this application overcome the problems ofexternal sipes noted above and are naturally more optimal as well, sincethey more closely parallel structurally the natural anatomicalstructures of the wearer's bare foot sole. As one example, simplyenveloping the outer surface of existing cushioning devices like gasbladders or foamed plastic Ethyl Vinyl Acetate (EVA) or Polyurethane(PU) with a new outer layer of material that is unattached (or at leastpartially unattached) thereby can creates if unglued an internal sipebetween the inner surface of the new compartment and the outer surfaceof the existing bladder/midsole component, allowing the two surfaces tomove relative to each other rather than being fixed to each other.

Especially in the common form of a slit structure seen in many exampleembodiments, the flexibility of the internal sipe is provided by thisrelative motion between opposing surfaces that in many the exampleembodiments are fully in contact with each other, again in contrast tothe separating surfaces of external sipes; such surface contact is, ofcourse, exclusive of any internal sipe media, which can be used as anadditional enhancement, in contrast to the flexibility-obstructingdebris unavoidably picked up by, and often clogging, open externalsipes. As a result, the footwear sole in which at least one integralinternal sipe insert or component is incorporated becomes much moreflexible, much more like the wearer's bare foot sole itself, so thatfoot sole can interact with the ground naturally. The resulting footwearsole with internal sipes has improved, natural flexibility, improvedcushioning from shock and shear forces, and better, more naturallystable support.

A limited use of internal sipes has also been described by the applicantin prior applications, including the examples shown in FIGS. 12A-12D,60A-60E, and 70-71 of both the applicant's '087 and '034 publishedApplications and '869 patent herein incorporated by reference above,which are generally unglued portions coinciding with lamination layerboundaries, such as between bottomsole and midsole layers. This olderapproach requires completely new and somewhat difficult approaches inthe assembly of the footwear sole during manufacture, as well assignificantly greater potential for problems of layer separation(especially bottom sole) since the inherent reduction in gluing surfacesmakes the remaining gluing surfaces critical and under increased load;significantly increased positional accuracy in the application of glueis required. Also, the use of lubricating media (and the potentialcontrol thereof, including by microprocessor) is also more difficult,since the sipe is formed by existing parts and is not discretelyenclosed with the new outer layer to contain the media, as it is in anew invention described in this application.

In contrast, a new invention of this application is a discrete device inthe form of an integral component that can easily be inserted as asingle simple step into the footwear sole during the manufacturingprocess or, alternatively, inserted in one single simple step by awearer (into the upper portion of a midsole insert, for example, muchlike inserting an insole into an shoe), for whom the new extra layerprovides buffering protection for the wearer from direct, potentiallyabrasive contact with a cushioning component (forming a portion of theinner, foot sole-contacting surface of the shoe sole, for example).

In addition, such a new invention allows easier and more effectivecontainment of a lubricating media (including media with specialcapabilities, like magnetorheological fluid) within the integralinternal sipe, so that the relative motion between inner surfaces of thesipe can be controlled by that media (and, alternatively, by directcomputer control); it avoids the need for the use of closed-cell midsolematerials or a special impermeable layer applied to the footwear solematerial to prevent the sipe media from leaking away.

The new invention also makes manufacturing easier and inherently moreaccurate, since the introduction of the fluid media can be bettercontrol during a separate process when the separate unitary insert orcomponent 510/511/513 is manufactured by itself, rather than attemptingto integrate that process into the already complex sole or orthoticmolding and assembly process.

Accordingly, it is a general object of one or more embodiments of theinvention to elaborate upon the application of the use of a device inthe form of an insertable integral component with one or more internalsipes to improve the flexibility, cushioning, and stability of footwearand other products.

It is still another object of one or more embodiments of the inventionto provide footwear having an integral insert or component with at leastone internal (or mostly internal) sipes, including slits or channels orgrooves and any other shape, including geometrically regular ornon-regular, such as anthropomorphic or animal shapes, to improveflexibility, cushioning and stability.

It is still another object of one or more embodiments of the inventionto include an insertable integral device with one or more internal sipesthat include a media such as a lubricant or glue of any usefulcharacteristic such as viscosity or any material, including amagnetorheological fluid.

It is another object of one or more embodiments of the invention tocreate a shoe sole with flexibility, support and cushioning that isprovided by siped chambers or compartments or bladders in the footwearsole or upper or orthotics. The compartments or chambers or bladders aresurrounded, partially or completely, by at least one internal (or mostlyinternal) sipe, including in the form of a slit, for use in any footwearsoles or uppers, or orthotic soles or uppers, and for other flexibility,cushioning, and stability uses in athletic equipment like helmets andapparel including protective padding and guards, as well as medicalprotective equipment and apparel, and other uses, such as protectiveflooring, improved furniture cushioning, balls and tires for wheels, andmany other uses.

It is another object of one or more embodiments of the invention tocreate footwear, orthotic or other products with at least one outerchamber; at least one inner chamber inside the outer chamber; the outerchamber and the inner chamber being separated at least in part by aninternal sipe, including in the form of a slit; at least a portion of aninner surface of the outer chamber forming at least a portion of aninner surface of the internal sipe; and the internal sipe providingincreased flexibility, cushioning, and stability for the footwear,orthotic or other product.

A further object of one or more embodiments of the invention is tocombine the integral insert or component with at least one internal sipewith the applicant's prior footwear inventions described and hereinincorporated by reference in this application, including removablemidsole structures and orthotics and chambers with controlled variablepressure, including control by computer.

These and other objects of the invention will become apparent from thesummary and detailed description of the invention, which follow, takenwith the accompanying drawings.

FIGS. 1-15, 17, and 22-79 show, as numeral 510, examples of a device orflexible insert including siped compartments 161 or chambers 188 orbladders (another term used in the art) for use in any footwear soles,including conventional soles 22 or the applicant's prior inventions,including footwear/shoe soles 28 and midsole inserts 145 as described inapplicant's published '087 application and Ser. No. 11/282,665 U.S.application published Nov. 9, 2006, as Pub. No. US 2006/0248749 A1incorporated by reference, or for orthotics 145 as described in theapplicant's published '034 U.S. Application, '869 patent, and WO02/09547 WIPO publication, as well as to be published by WIPO PCTApplication Number PCT/US2005/042341, all incorporated by referenceherein, including for uppers for footwear or orthotics (or includinguppers), or for other flexibility uses in athletic equipment likehelmets and apparel including protective padding and guards, as well asmedical protective equipment and apparel, and other uses, such asprotective flooring, improved furniture cushioning, balls and tires forwheels, and other uses.

The device or flexible insert with siped compartments or chambers 510include embodiments like two or more of either compartments 161 orchambers 188 or bladders (or a any mix including two or more of acompartment, a chamber, and a bladder) that are separated at least inpart or in several parts or mostly or fully by an internal sipe 505. Theflexible insert 510 can be inserted during assembly of an article by amaker or manufacturer or is insertable by a user or wearer (into anarticle like a shoe, for example, as part of a removable midsole insert145 described above), or integrated into the construction of a device asone or more components.

Siped compartments or chambers 510 include example embodiments such asFIGS. 1-15, 17, and 22-79 which generally show at least one innercompartment 161 or chamber 188 inside at least one other outercompartment 161 or chamber 161; and the two compartments/chambers161/188 being separated by an internal sipe 505.

One practical example embodiment of the invention is any priorcommercial embodiment of Nike Air™ gas bladder or compartment (liketypical examples in FIGS. 12-16 of U.S. Pat. No. 6,846,534, which ishereby incorporated by reference) that is installed unattached, as is,located within the space enclosed partially or fully by a new, slightlylarger outer compartment of one additional layer of the same or similarmaterial, with the same or a simpler or the simplest geometric shape;that is, not necessarily following indentations or reverse curves, butrather incorporating straighter or the straightest lines, as seen incross-section: for example, following the outermost side curvature seenin FIGS. 12-16, but with upper and lower surfaces that are substantiallyflat and parallel (or curved and parallel), to facilitate ease ofmovement between the two surfaces of the sipe 505 formed, increasing theresulting flexibility.

The new additional, outer compartment thus thereby has created by itspresence an internal sipe 505 between the two unconnected compartments.The new internal sipe 505 provides much greater flexibility to anyfootwear sole 22 or 28, since it allows an inner, otherwise relativelyrigid Nike Air™ compartment structure to become an inner compartment 501(instead of typically being fixed into the other materials such as EVAof the footwear sole) to move freely inside the new outer compartment500, which becomes a new compartment that is fixed to the footwear sole,rather that the conventional Nike Air™ bladder. The flexibilityimprovement allows the shoe sole to deform under a body weight load likea wearer's bare foot sole, so that stability is improved also,especially lateral stability.

The result is that the conventional, inner Nike Air™ compartment—nowcontained by a new outer compartment—can move easily within the overallfootwear sole, allowing the sole to bend or flex more easily in parallelwith the wearer's bare foot sole to deform to flatten under a bodyweight load, including during locomotion or standing, so that footwearsole stability is improved also, especially lateral stability. Theextent to which the inner Nike Air™ compartment is “free-floating”within the new outer compartment can be controlled or tuned, forexample, by one or more attachments (permanent or adjustable) to theouter compartment or by the media in the internal sipe.

The internal sipe 505 includes at least two surfaces that can moverelative to each other to provide a flexibility increase for a footwearsole so that the shape of the footwear sole can deform under a bodyweight load to better parallel to the shape of the barefoot sole of awearer under a same body weight load. The relative motion between thetwo internal sipe 505 surfaces increases the capability of the footwearsole to bend during locomotion under a wearer's body weight load tobetter parallel the shape of said wearer's bare foot sole.

In an analogous way, especially to the thicker heel portion of a typicalshoe sole, a thick urban area telephone book has in effect hundreds ofmostly “internal sipes”, each page being in effect separated by ahorizontal internal slit from each adjacent page, each of which therebyis able to move freely relative to each other, resulting in a flexibletelephone book that bends quite easily, while at the same timerelatively stable when a vertical force like body weight is applied.

In contrast, if the same wood fiber material with the same dimensions asa thick telephone book were formed instead into a single piece with nopages, like a solid particle board, it would be quite rigid.

If, instead, the sipes were rotated 90 degrees into vertical slits andopen to the bottom, so that the spine of the telephone book is on top,those external sipes would also provide a substantial amount offlexibility, but at the cost of excessive instability when a verticalforce like body weight is applied.

Also, the sliding motion between internal support surfaces within theshoe sole 28 allowed by internal sipe 505 in response to torsional orshear forces between a wearer's foot and the ground assists incontrolling and absorbing the impact of those forces, whether sudden andexcessive or chronically repetitive, thereby helping to protect thewearer's joints from acute or chronic injury, especially to the ankles,knees, hips, lower back, and spine.

A benefit of the siped compartments/chambers 510 is that, as a singleunitary component, it can be used in any conventional manner inconstructing the footwear sole 28, generally like that used with aconventional single layer compartment such as used in Nike Air™; i.e.the outer surface of 510 can, as a useful embodiment, adhere to theadjacent materials like plastic such as PU (polyurethane) or EVA (ethylvinyl acetate) or other plastic or rubber of the footwear sole thatcontact the 510 component, just as would be the case with the outersurface of existing single compartment 161 or chamber 188 of commercialexamples of Nike Air™. However, the internal sipe 505 formed by the useof an inner compartment/chamber 501 in the siped compartment/chamber 510provides flexibility in a footwear sole 28 that is absent in therelatively rigid footwear sole 28 formed with a conventional, singlelayer compartment 161 or chamber 188 of the many Nike Air™ commercialexamples.

The sipe surfaces can in one useful example embodiment be formed by theinner surface (or part or parts of it) of the outer compartment 500 andthe outer surface (or part or parts of it) of the inner compartment 501.Such sipe surfaces can be substantially parallel and directly contacteach other in one useful embodiment example, but the two surfaces aregenerally not attached to each other, so that the sipe surfaces can moverelative to each other to facilitate a sliding motion between the twosurfaces.

The sipe surfaces can be in other useful forms that allow portions ofthe surfaces to be proximate to each other in an unloaded condition,rather than contacting; such surfaces can make partial or full directcontact under a wearer's body weight load (which can vary from afraction of a “g” to multiple “g” forces during locomotion) or remainsomewhat separated; the amount of sipe surface area making directcontact can also vary with a wearer's body weight load. The sipessurfaces also may not be parallel or only partially parallel, such asthe areas of direct surface contact or proximal surface contact.

To preclude the surfaces of the internal sipe 505 from directlycontacting each other (whether loaded or unloaded), the sipe surfacescan include an internal sipe media 506 located between the surfaces toreduce friction by lubrication and increase relative motion andtherefore flexibility. Useful example embodiments of the internal sipemedia 506 include any useful material known in the art (or equivalent),such as a liquid like silicone as one example, a dry material likepolytetrafluoroethylene as another example, or a gas like that used inNike Air™ as a further example. The media 506 can be located in all ofthe sipe 505 or only part or parts, as shown in FIGS. 1-6.

The media 506 can be used to decrease (or increase) sliding resistancebetween the inner surfaces of the sipe; for example, to lubricate withany suitable material known in the art. The internal sipe media 506 isan optional feature.

The siped compartments/chambers 510 can be located anywhere in thefootwear sole or orthotic or upper and can be used in otherapplications, including non-footwear applications where flexibilityincreases are useful). The siped compartments/chambers 510 can be made,for example, with any methods and materials common in the footwear artsor similar arts or equivalents, like those in various Nike Air™; see forexample U.S. Pat. Nos. 4,183,156 and 4,219,945 to Rudy (which showfluid-filled bladder manufacturing through a flat sheet bondingtechnique), 5,353,459 to Potter et al. (which shows fluid-filledbladders manufactured through a blow-molding process), as well as U.S.Pat. No. 6,837,951 and FIGS. 12-16 of U.S. Pat. No. 6,846,534, all ofwhich patents are herein incorporated by reference) or similarcommercial examples like Reebok DMX™ compartments in its original form,as seen for example U.S. Pat. No. 6,845,573 (herein incorporated byreference), column 5, line 41 to column 6, line 9), or New BalanceN-ergy™ (see for example FIG. 1 of WIPO Pub. No. WO 00/70981 A1, butnote that, as a example, at least the initial production versions of theN-ergy compartment can have less rigidity to allow better flexibility)or Asics Gel™ (many versions) compartments or future equivalents of any,or with less common materials, such as fibers described aboveincorporated into or on the surface of the material of the sipedcompartment/chambers 510, including either elastic fibers or inelasticfibers or a mix. The siped compartment/chambers 510 can be of anypractical number in a footwear sole or any shape, of which usefulexample embodiments include regular geometric shapes or irregularshapes, including anthropomorphic or animal shapes; and the 510 numberor shape can be symmetrical or asymmetrical, including between right andleft footwear soles.

Either of the compartments 161 or chambers 188 of the sipedcompartment/chambers 510 (or 511 or 513) can include one or morestructural elements 502 like those common in the footwear art such as inNike Air™ as noted in the above cited Rudy and Nike patents, alsoincluding Tuned Air™ (See for example U.S. Pat. No. 5,976,451 to Skajaet al, which is herein incorporated by reference and which showsmanufacturing of fluid-filled bladders through a vacuum-forming process)or Zoom Air™ (See for example FIGS. 1-3 of U.S. App. No. 2005/0039346A1, which is herein incorporated by reference); a number of exampleembodiments of inner compartments 501 with structural elements 502 areshown in the FIGS. 1A, 9, 13, and 14. The structural elements 502 can bemade of any useful material known in the art and constructed in anymanner known in the art. FIGS. 25A and 26A show similar exampleembodiments wherein the structural elements 502 of the inner compartment501 are formed with a specific shape and foamed plastic material such asPU or EVA like that of Nike Shox™ (See U.S. Pat. Nos. 5,353,523,5,343,639, and 6,851,204, which are herein incorporated by reference)and Nike Impax™ (U.S. Pat. No. D500,585 S, which is herein incorporatedby reference), respectively, and can be affixed to the inner compartment501, which can be reinforced as necessary (instead of to rigid lowerand/or upper plates); the lower surface of the outer compartment 500 canbe attached to an outer sole, at least in part or an outer sole can beintegrated into the outer compartment 500 by thickening, for example, orincorporating rubber or rubber substitute material. Other commercialexisting examples that can be similarly modified as a device or flexibleinsert or component 510 (or 511 or 513) are Adidas a³™ Energy-ManagementTechnology and Adidas Ground Control System (GPS)™, and Reebok DMX™Shear Heel or other cushioning technologies.

Also, as shown in the example embodiments of FIGS. 26B and 25B, sincefoamed plastic material does not require containment (unlike a gas,liquid, or most gels), if the structural elements 502 are sufficientlyinterconnected, like for example Nike Impax™ in FIG. 26B, or if theseparate support columns 32 and midsole wedge 40 of Nike Shox™ aremodified to interconnect like the example shown in FIG. 25B, then thoseconnected structural elements 502 can form an integral inner compartment501, the outer surface of which can form an internal sipe 505 with thenew outer compartment 500. The interconnection can be complete, witheach structural elements 502 connected to at least the closest otherelements 502, as shown, or mostly complete, or partial. The Shox™support columns 32 can be any practical number, such as existingexamples of four or five or six (all commercially available) or more inthe heel and many more in the forefoot of the shoe sole 22 or 28, for atotal of eleven in existing commercial examples.

Any of the compartments or chambers 161/188 of the siped compartment 510can be permanently or temporarily attached one to another with at leastone attachment 503 of any useful shape or size or number or position;embodiment examples are shown in FIGS. 1A, 2A, 3A, 4A, 5A, 6A, and 8.Anthropomorphic designs would suggest including positioning attachments503 on the internal sipe 505 closest to a wearer's foot sole as a usefulembodiment, so that the remaining sipes 505 would have a U shape incross-section, like the structure of human foot sole fat pads, which areanalogous to the cushioning midsole and midsole components of footwearsoles.

The attachments 503 can be simply passive (i.e. static) or activelycontrolled by electronic, mechanical, electromagnetic, or other usefulmeans. The attachments 503 can, for example, be designed to break awayas a failsafe feature to compensate for a predetermined extremetorsional load, for example, to reduce extreme stress on critical joints(in lieu of a wearer's cartilage, tendons, muscle, bone, or other bodyparts being damaged); the attachments 503 can then be reset or replaced(or, alternatively, return automatically upon relief of extreme stressto a normal position).

Example embodiments of the compartments and chambers 500/501 can includea media 504 such as a gas (like that used in Nike Air™ or ambientatmospheric air), a liquid or fluid, a gel, a foam (made of a plasticlike PU or EVA, both of which are common in the footwear art, orequivalent, or of a rubber (natural or synthetic) or blown rubber or arubber compound or equivalent or of another useful material or of acombination of two or more of the preceding foam plastic/rubber/etc.) ora useful combination of one or more gas, liquid, gel, foam, or otheruseful material.

FIG. 16 shows an example embodiment of chambers 188 for any footwearsoles, including conventional, or other flexibility uses with anelectromagnetic shock absorption system similar to, for example, theCadillac™ “Magnetic Ride Control” system, wherein magnetically sensitivemetal particles 507 suspended in a shock absorbing fluid 508 are madeless fluid in effect by controlling, on for example a millisecond basis,an electromagnetic field-creating circuit 509 that aligns the metalparticles 507 into a flow resistant structure. The fluid 508 is thus amagnetorheological fluid, that is, a fluid which generally solidifiesinto a pasty consistency when subject to a magnetic field.

FIG. 17A shows an example embodiment like FIG. 11N of applicant'sincorporated published '087, '034 and '665 Applications and '869 patentwherein the flow between chambers 188 is controlled by controlling theflow resistance of the fluid 508 by the circuit 509 located to affectthe fluid 508 in one or more of the chambers 188; alternatively, theflow can be controlled by the circuit 509 being located between thechambers.

FIG. 17A shows a similar embodiment and view to that shown in FIG. 15,but including an electromagnetic shock absorption system. FIG. 17B is aclose-up view of an embodiment like FIG. 7, but showingmagnetorheological fluid 508 located within an internal sipe 505.

The FIG. 16-17 example embodiments can be located anywhere in thefootwear sole (and can be used in other applications, includingnon-footwear applications where flexibility increases are useful). TheFIG. 16-17 embodiments can be made with any materials common in thefootwear art, like those in various Nike Air™ commercial examples, orfuture equivalents, or with less common materials, such as fibersdescribed earlier, including either elastic fibers or inelastic fibersor a mix. The FIG. 16-17 example embodiments can be of any practicalnumber in a footwear sole, or any shape, of which useful embodimentsinclude regular geometric shapes or irregular shapes, includinganthropomorphic shapes; and the number or shape can be symmetrical orasymmetrical, including between right and left footwear soles.

Also, any inventive combination that is not explicitly described abovein the examples shown in FIGS. 16-17 is implicit in the overallinvention of this application and, consequently, any part of the exampleembodiments shown in preceding FIG. 16-17 and/or associated textualspecification can be combined with any other part of any one or moreother elements of each other or the invention or prior art examplesdescribed in FIGS. 1-15 and 18-79 and/or associated textualspecification and/or, in addition, can be combined with any one or moreother elements of each other or the inventive or prior art examplesshown in prior published FIGS. 1-75 of the '869 patent and the '087,'034 and '665 Applications, as well as additional FIGS. 76-82 of the'665 Application, and also added FIGS. 1-43 of the '887 Application.

FIG. 18 shows an example embodiment of a flexible insert or component511 including a single compartment/chamber 161/188 or bladder with anassociated internal sipe 505 component, again for any footwear sole,including conventional 22, or other flexibility uses (such as thosedescribed above relative to insert 510), to form a single unitary sipedcompartment or chamber; the sipe 505 can extend to part or all of oneside of the single compartment 500, as shown, or the sipe 505 can extendaround portions of the other sides of the singlecompartment/chamber/bladder 500; FIG. 18B shows an example embodiment ina horizontal plane view of 511. The flexible insert 511 can be insertedduring assembly of an article by a maker or manufacturer or isinsertable by a user or wearer (into an article like a shoe, forexample, as part of a removable midsole insert described above), orintegrated into the construction of an article as one or morecomponents.

A benefit of the single siped compartment/chamber/bladder 511 is that,as a single unitary component like 510, it can be used in a conventionalmanner in constructing the footwear sole 28, like that used with aconventional single layer compartment in Nike Air™; i.e. the outersurface of 511 can, as a useful embodiment, adhere to the adjacentmaterial of the footwear sole that contact the 511 component, just aswould the outer surface of a single compartment 161 or chamber 188.However, the internal sipe 505 component of the sipedcompartment/chamber/bladder 511 provides flexibility in a footwear sole28 that is absent in the relatively rigid footwear sole 28 formed with aconventional, single layer compartment 161 or chamber 188.

The siped compartments/chamber/bladder 511 can be located anywhere inthe footwear sole (and can be used in other, non-footwear applicationswhere flexibility increases are useful). The sipedcompartment/chamber/bladders 511 can be made with any materials commonin the footwear art, like those in various Nike Air™ commercialexamples, or future equivalents, or with less common materials, such asfibers described earlier, including either elastic fibers or inelasticfibers or a mix. The siped compartment/chamber/bladders 511 can be ofany practical number in a footwear sole, or any shape, of which usefulembodiments include regular geometric shapes or irregular shapes,including anthropomorphic shapes; and the number or shape can besymmetrical or asymmetrical, including between right and left footwearsoles.

FIG. 18C is an exploded perspective view showing the relationship of aninsert device 511, which has a compartment or chamber or bladder and aninternal sipe, with a midsole 148, bottom sole 149, and upper 21 of ashoe or any other footwear. The midsole 148 and bottom sole 149 (and anyadditional midsole or other layers not shown) together form a shoe solewhich can be any footwear sole, including any conventional sole 22 orany sole 28 according to one of the applicant's patents or applications.In the simple example shown, the device 511 can be inserted during aconventional manufacturing or assembly process or by a footwear wearerand can be located anywhere in the footwear sole and/or upper.

Also, any inventive combination that is not explicitly described abovein the example shown in FIG. 18 is implicit in the overall invention ofthis application and, consequently, any part of the example embodimentsshown in preceding FIG. 18 and/or associated textual specification canbe combined with any other part of any one or more other elements of theinvention examples described in FIGS. 1-17 and 19-79 and/or associatedtextual specification and/or, in addition, can be combined usefully withany one or more other elements of each other or the inventive or priorart examples shown prior published FIGS. 1-75 of the '869 patent and the'087, '034 and '665 Applications, as well as additional FIGS. 76-82 ofthe '665 Application, and also added FIGS. 1-43 of the '887 Application.

FIG. 19A shows an example embodiment of a flexible insert or component513 forming a unitary internal sipe for any footwear sole or orthotic orupper, including conventional sole 22, or other flexibility uses (suchas those described above relative to insert 510), the embodiment shownemploying a single internal flexibility sipe 505 in the form of a slit;FIG. 19B shows an example embodiment in a horizontal plane view of FIGS.19A, 20A, and 21A. Multiple unitary internal sipes 513 can be usedindependently or synergistically anywhere in a footwear sole in otheruseful embodiments not shown; the sipes 513 can be stacked proximate toone another or apart, as viewed in a frontal or sagittal plane, forexample; or the sipes 513 can overlap, as viewed in a horizontal plane,for example. The flexible insert 513 can be inserted during assembly ofan article by a maker or manufacturer or is insertable by a user orwearer (into an article like a shoe, for example, as part of a removablemidsole insert described above), or integrated into the construction ofan article as one or more components.

In one useful example embodiment, the unitary internal sipe 513 can bemade as a separate sole component like an extremely thin conventionalgas compartment similar to a Nike Air™ compartment, but without thetypical internal compartment structures (which in another usefulembodiment can be present in some form if unattached to at least oneinner surface so that relative motion between inner surfaces can occurto provide increased flexibility).

A benefit of the unitary internal sipe 513 is that, as a singleinsertable unitary component like 510 and 511, it can be used in aconventional manner in constructing the footwear sole 28, roughly likethat used with a conventional single layer compartment in Nike Air™;i.e. the outer surface of 513 can, as a useful embodiment, adhere to theother portions of the footwear sole that contact the 513 component, justas would the outer surface of a single compartment 161 or chamber 188.

The unitary internal sipe 513 can be located as a separate componentanywhere in the footwear sole (and can be used in other applications,including non-footwear applications where flexibility increases areuseful). The insertable unitary internal sipe 513 can be made with anymaterials common in the footwear art, like those in various Nike Air™commercial examples, or future equivalents, or with less commonmaterials, such as fibers described earlier, including either elasticfibers or inelastic fibers or a mix. The unitary internal sipe 513 canbe of any practical number in a footwear sole, or any shape, of whichuseful example embodiments include regular geometric shapes or irregularshapes, including anthropomorphic shapes; and the number or shape can besymmetrical or asymmetrical, including between right and left footwearsoles.

FIG. 19C is an exploded perspective view showing the relationship of aninsert device 513, which can be a thin compartment or chamber or bladderforming an internal sipe such as a slit, with a midsole 148, bottom sole149, and upper 21 of a shoe or any other footwear. The midsole 148 andbottom sole 149 (and any additional midsole or other layers not shown)together form a shoe sole which can be any footwear sole, including anyconventional sole 22 or any sole 28 according to one of the applicant'spatents or applications. In the simple example shown, the device 513 canbe inserted during a conventional manufacturing or assembly process orby a footwear wearer and can be located anywhere in the footwear soleand/or upper.

FIG. 20A shows the FIG. 19A example embodiment of a unitary internalsipe 513 positioned as a separate component in an embodiment of afootwear sole 28; alternatively, in another example embodiment notshown, the unitary internal sipe 513 can be completely enclosed inconventional midsole material like PU or EVA or similar material.

FIG. 20C shows a frontal plane cross section of an insert device 513 asa thin compartment or chamber or bladder 501 (or walls 512) forming aninternal sipe 505 such as a slit that is located in any footwear sole,including any conventional sole 22 or any sole 28 according to one ofthe applicant's patents or applications; the sole example shown is asingle piece, but can include any number of layers (including forexample multiple midsole or other layers), at least including a midsole148 and outsole 149.

FIG. 21A shows the unitary internal sipe 513 in an example embodimentincluding three separate internal flexibility sipes 505, which in oneembodiment can be completely enclosed in conventional midsole materialsuch as PU or EVA or similar material. Generally, unitary internal sipes513 can thus be subdivided into any practical number of smaller unitaryinternal sipes that are aggregated together (or can be positioned alone,as described earlier).

Also, any inventive combination that is not explicitly described abovein the examples shown in FIGS. 19-20 is implicit in the overallinvention of this application and, consequently, any part of the exampleembodiments shown in preceding FIGS. 19-20 and/or associated textualspecification can be combined with any other part of any one or moreother elements of each other or the invention or prior art examplesdescribed in FIGS. 1-18 and 21-79 and/or associated textualspecification and/or, in addition, can be combined usefully with any oneor more other elements of each other or the inventive or prior artexamples shown in prior published FIGS. 1-75 of the '869 patent and the'087, '034 and '665 Applications, as well as additional FIGS. 76-82 ofthe '665 Application, and also added FIGS. 1-43 of the '887 Application.

FIG. 22 shows an example embodiment of a flexible insert or component510 with siped compartment/chamber/bladders used in the footwear upper21 for use in embodiments like the Reebok Pump™ and Pump 2.0™; theflexible insert or component 510 can be positioned anywhere in upper 21,including an orthotic; 511 and 513 can be used also.

FIG. 23 shows an example embodiment of a flexible insert or component510 that is substantially forming the footwear upper 21 in part of theheel and which can be used anywhere else are in all of the upper 21.Note also that the flexible insert or component 510 shown as an examplein FIG. 23 also shows the flexible insert or component 510 positions sothat it is located in both the upper 21 and in the shoe sole or in bothan orthotic and orthotic upper; 511 and 513 can be used also.

Also, any inventive combination that is not explicitly described abovein the examples shown in FIGS. 22-23 is implicit in the overallinvention of this application and, consequently, any part of the exampleembodiments shown in preceding FIGS. 22-23 and/or associated textualspecification can be combined with any other part of any one or moreother elements of each other or the invention or prior art examplesdescribed in FIGS. 1-21 and 24-79 and/or associated textualspecification and/or, in addition, can be combined usefully with any oneor more other elements of each other or the inventive or prior artexamples shown in prior published FIGS. 1-75 of the '869 patent and the'087, '034 and '665 Applications, as well as additional FIGS. 76-82 ofthe '665 Application, and also added FIGS. 1-43 of the '887 Application.

FIGS. 24A and 24B show, in frontal plane cross section, two exampleembodiments of any helmet 550 for any use with a cushioning helmet liner551 including an inner flexible insert or component 510; any usefulnumber of flexible inserts or components 510 can be used; flexibleinsert or components 511 and 513 can be used also. The inventionincludes any helmet 550 (or part or parts of the helmet) with a liner551 with one or more internal sipes 505 of any form previously describedin this application and any material known in the art located anywherebetween the outer surface and inner surface of the helmet liner 551.

FIGS. 24C and 24D show, in frontal plane cross section, two exampleembodiments of any helmet 550 for any use including one or more internalsipes 505 of any form previously described in this application and anymaterial known in the art located anywhere between the outer surface andinner surface of the helmet 550, and can include, for example, a shockand shear-absorbing media 504 as previously described in thisapplication.

Also, any inventive combination that is not explicitly described abovein the examples shown in FIGS. 24A-24D is implicit in the overallinvention of this application and, consequently, any part of the exampleembodiments shown in preceding FIGS. 24A-24D and/or associated textualspecification can be combined with any other part of any one or moreother elements of each other or the invention or prior art examplesdescribed in FIGS. 1-23 and 25-79 and/or associated textualspecification and/or, in addition, can be combined usefully with any oneor more other elements of each other or the inventive or prior artexamples shown in prior published FIGS. 1-75 of the '869 patent and the'087, '034 and '665 Applications, as well as additional FIGS. 76-82 ofthe '665 Application, and also added FIGS. 1-43 of the '887 Application.

Also, any inventive combination that is not explicitly described abovein the example shown in FIG. 24 is implicit in the overall invention ofthis application and, consequently, any part of the example embodimentsshown in preceding FIG. 24 and/or associated textual specification canbe combined with any other part of any one or more other elements of theinvention or prior art examples described in FIGS. 1-23 and 25-79 and/orassociated textual specification and/or, in addition, can be combinedusefully with any one or more other elements of the inventive or priorart examples shown in prior published FIGS. 1-75 of the '869 patent andthe '087, '034 and '665 Applications, as well as additional FIGS. 76-82of the '665 Application, and also added FIGS. 1-43 of the '887Application.

FIGS. 25A and 25B, as well as FIGS. 26A and 26B, show a heel section ofa footwear sole or orthotic with an example of a flexible insert orcomponent 510 using specific examples of the structural elements 502based on commercial examples of Nike Shox™ and Nike Impax™. FIGS. 25Aand 26A show an example of those structural elements of foam materialcontained and affixed within an inner compartment 501. Since use of afoamed material as a media does not require containment to maintain itsstructure and function (in contrast to a gas, liquid, or most gels), afoamed material do not require a separate inner compartment 501 in orderto form an internal sipe 505 with the new outer compartment 500, asnoted under the section on compartment 500/501 media 504 below; thus, asshown in the examples of FIGS. 25B and 26B, suitably configured (interms of interconnections and shape, for example) structural elements502 of a foamed material can form an integral inner compartment 501creating an internal sipe 505 with outer compartment 500.

FIG. 26C shows an example in a horizontal plane cross-section of afootwear sole 22 of a device or flexible insert or component 510 inwhich the inner compartment 501 includes a flexible shank 514 located inthe media 504 in the general area of the instep of the shoe sole betweenthe heel area and the forefoot area. The flexible shank 514 can be madeof any rigid or semi-rigid material including plastic, metal, andcomposites including carbon-fiber common in the art and can have sipes151, of which a vertical slit is one example among a very many wellknown in the art, that are generally oriented from the area of the heelto the area of the forefoot (including at an angle) so that the shoesole 22 is flexible enough to flatten in following the deformationmotion of a wearer's foot sole in a full range of pronation andsupination motion, while remaining sufficiently rigid to supportnaturally the instep area of the shoe sole 22, a area that is relativelythin (often with tapered thickness) and therefore not ground-contactingin many common footwear soles popular in the art and therefore unstablewithout shank support, which is well known in the art but which istypically too narrow to support directly the base of a wearer's fifthmetatarsal and too rigid in a frontal plane to follow a wearer's lateralpronation/supination motion.

FIG. 26D shows two different examples of versions of the flexible shank514 in frontal plane cross section. The upper version shows on the leftside vertical sipes 151 as slits that penetrate the shank fully andwhich can be held together, especially during assembly, by an attachedfiber (or other material, like foam, for example) layer, while on theright side is another variation of sipes (among the vast number ofpossibilities discussed in the applicant's prior patents), which areslits 151′ that do not fully penetrate the flexible shank 514. The lowerversion shows an example of inverted V shaped channels as another sipevariation, with the left side showing full or near full penetration (andagain, a fiber or other layer can be attached) and the right sideshowing the channels connected by portions of the flexible shank 514.

Also, any inventive combination that is not explicitly described abovein the example shown in FIGS. 25-26 is implicit in the overall inventionof this application and, consequently, any part of the exampleembodiments shown in preceding FIGS. 25-26 and/or associated textualspecification can be combined with any other part of any one or moreother elements of each other or the invention or prior art examplesdescribed in FIGS. 1-24 and 27-79 and/or associated textualspecification and/or, in addition, can be combined usefully with any oneor more other elements of each other or the inventive or prior artexamples shown in prior published FIGS. 1-75 of the '869 patent and the'087, '034 and '665 Applications, as well as additional FIGS. 76-82 ofthe '665 Application, and also added FIGS. 1-43 of the '887 Application.

FIG. 27 shows in cross-section an example of any ball 530 with one ormore internal sipes 505 of any shape located between the outer surfaceof the ball and an inner surface. The ball includes a structure like thedevice or flexible insert 510 above, with an innercompartment/chamber/bladder 501 in a typical example having a media 504,which can be pressured gas like air that is sealed (like a tennis ball)or controlled by a valve (not shown) common in the commercial art, likea basketball, and with an outer compartment/chamber/bladder 500.Alternatively, the ball can be structured like a typical golf ball witha solid or relatively solid core (with one or more layers of material)as media 504, which would be separated from the tough outer layer by aninternal sipe 505, which can be made to reduce the uncontrolled spin ofan offcenter shot like a slice or hook, since any spin imparted to thecompartments at the instant of club contact with the ball would becomerelatively disconnected after contact, with the outer compartmentencountering air resistance to its spin, while the core of the innercompartment 501 would encounter friction from the internal sipe 505surfaces. A similar design and construction approach involving andinternal sipe 505 can be used with other devices like skis, bats, toolhandles.

Also, any inventive combination that is not explicitly described abovein the example shown in FIG. 27 is implicit in the overall invention ofthis application and, consequently, any part of the example embodimentsshown in preceding FIG. 27 and/or associated textual specification canbe combined with any other part of any one or more other elements of theinvention or prior art examples described in FIGS. 1-26 and 28-79 and/orassociated textual specification and/or, in addition, can be combinedusefully with any one or more other elements of the inventive or priorart examples shown in prior published FIGS. 1-75 of the '869 patent andthe '087, '034 and '665 Applications, as well as additional FIGS. 76-82of the '665 Application, and also added FIGS. 1-43 of the '887Application.

FIG. 28A shows in cross-section an example of a tire 535, such as for awheel of a transportation vehicle, with a device 510; the internal sipe505 and/or inner compartment/chamber/bladder 501 can be pressured or not(valve not shown). As shown in the example, innercompartment/chamber/bladder 501 can have one or more direct attachments503 to the wheel and the structural elements shown can be made of anyuseful material as is conventional in the art, including plastic and/orplastic composite and/or carbon fiber. The outercompartment/chamber/bladder 500 can be abbreviated to cover only part ofinner compartment/chamber/bladder 501, as shown in FIG. 28, (possiblypressure-sealed to the wheel like a conventional automobile tire andwheel); the outer compartment/chamber/bladder 500 can also beabbreviated further to cover only a lesser portion, including at least atread portion, which can include rubber (natural or synthetic, as canother or all parts of the outer compartment 500. FIG. 28B shows in aside view cross-section an example of shape of structural elements 502of the inner compartment 501 (not shown for simplicity).

Also, any inventive combination that is not explicitly described abovein the example shown in FIG. 28 is implicit in the overall invention ofthis application and, consequently, any part of the example embodimentsshown in preceding FIG. 28 and/or associated textual specification canbe combined with any other part of any one or more other elements of theinvention or prior art examples described in FIGS. 1-27 and 29-79 and/orassociated textual specification and/or, in addition, can be combinedusefully with any one or more other elements of each other or theinventive or prior art examples shown in prior published FIGS. 1-75 ofthe '869 patent and the '087, '034 and '665 Applications, as well asadditional FIGS. 76-82 of the '665 Application, and also added FIGS.1-43 of the '887 Application.

FIG. 29A shows, in sagittal plane cross sections, two examples of priorart human breast implants, the first inserted over pectoral muscle andthe second inserted under pectoral muscle. FIG. 29B shows an example ofa human breast implant 540 with a siped compartment/chamber/bladder 510in any of the forms described earlier in this application. The breastimplant 540 can be located like either of the prior art examples in FIG.29A or in another position, or, alternatively, can be incorporated in apad worn externally to the wearer's body. Similar implants or prostheticdevices 540 incorporating a siped compartment/chamber/bladder 510including of anatomical or anatomically compatible shape can be usedanywhere else in or on the human body, or in or on the body of an animalor other biological entity, utilizing any material in the known implantor other art, including new equivalents, for both functional and/orcosmetic purposes, including external use. More generally, the implantor prosthetic device 540 can be any pad incorporating one or moreinternal sipes 505 of any 510/511/513 form described earlier in thisapplication located anywhere within the implant 540 (or connecting tothe outer surface of 500) In one example embodiment, the media 504contained by the inner compartment 501 can be a material like silicone,the media 504 contained by the inner compartment 501 can be a materiallike silicone, while the sipe area 505 can contain a material likewater.

FIGS. 30A-30D show cross sectional examples of any structural or supportelement 550 in any device, including mechanical, electro-mechanical,architectural, electronic, optical, or biological, including a beam orstrut, or a tool or racquet handle or grip, shaft or body, or head, thatincorporates a siped compartment/chamber/bladder 510 of any formdescribed earlier in this application located anywhere within thestructural or support element 550.

Reference numeral 28 refers to the applicant's footwear sole inventionsin this and prior footwear/orthotic applications and patents, butreference numeral 28 also refers to orthotics and/or corrective footwearin this application, as well as in the applicant's prior footwearapplications and patents that are incorporated by reference herein. Thisis because footwear soles 28 themselves can be custom modified in amanner conventional to the orthotic and/or corrective shoe art withindividualized correction made to the footwear sole 28 as if the entiresole 28 were an orthotic device, rather than just to an orthotic insert145; potentially included are differing corrections between right andleft footwear soles 28 as necessary, as is conventional in theorthotic/corrective shoe art.

Reference numeral 148 refers to midsole, a middle sole layer between thebottom sole and the shoe upper; the midsole has been in commercial usefor about forty years, primarily to provide cushioning in modernfootwear in the form of relatively soft foamed plastic or otherelastomeric material that compresses relatively easily under the bodyweight load of a wearer of a footwear/orthotic sole 28. Standard midsolematerial in the footwear art is the use of a foamed plastic like EVA orPU, as well as other foamed elastomeric materials indicated in paragraphnumber 0178 of the '087 Application incorporated by reference hereinearlier or equivalent materials.

Since the primary function of midsole 148 in the footwear art is toprovide cushioning, such foamed plastics in general use are relativelysoft, ranging typically from a fairly soft 30 durometers on a Shore AHardness Scale to a relatively harder 60 durometers and about 40-70durometers on the Asker C Hardness Scale.

It is the applicant's view that these standard ranges of midsolehardness are excessively soft in order to compensate for the generalcommercial use of a non-optimal, not sufficiently anthropomorphic shapefor the basic structure of footwear/orthotic soles 28. That is, thesoftness of the midsole material allows conventional footwear/orthotics22, especially the sides, to bend up more easily into a shape more likethat of a wearers foot sole subjected to a body weight load. Theapplicant's firm view that the more direct and effective approach is toobviate the need to compensate by using an anthropomorphically shapedfootwear/orthotic sole 28 structure, as described previously by theapplicant in this and the applicant's prior footwear applications andpatents incorporated by reference herein. Moreover, recent humanbiomechanics research indicates a counter-intuitive result: that softermidsole cushioning actually causes higher impact forces for a wearer.

Consequently, based on the foregoing, the only direct way to achieve alower, more natural level of impact forces on a wearer is to form a newcombination of significantly firmer midsole material together with thecorrect, anthropomorphic footwear/orthotic sole 28 shape previouslydescribed by the applicant. However, increased firmness alone results ininstability, since footwear/orthotic soles 28 that are rounded and thatdo not flatten easily like the rounded sole of an unloaded wearer's footdoes under a body weight load will function instead roughly like a rigidrocking chair, not a foot sole, which is rounded but flattens easilyunder body weight.

Therefore, increased material firmness must be newly combined withincreased structural flexibility provided by the applicant's internalsipe inventions 510/511/513 in order to create footwear/orthotic soles28, or removable midsole/orthotic inserts 145, that are both roundedlike the shape of a wearer's unloaded foot sole and deformable so as toflatten like that wearer's rounded foot sole flattens under a bodyweight load. As a direct result, at the same time impact forces on awearer are reduced to a natural, bare foot level, while “energy return”is increased to a natural, bare foot level, instead of the relativeenergy loss (actually, “negative energy return”) of conventionalathletic shoe soles compared to the bare foot.

The use of midsole 148 material that is firmer than that which isstandard in the footwear art therefore has significant functionalbenefits in combination with the applicant's internal sipe inventions.Such relatively firm or hard midsole 148 material for footwear/orthoticsoles 28 and inserts 145 can usefully be on a Shore A Hardness Scale,for example, greater than 60 durometers, such as at least 65 durometers,at least 70 durometers, at least 75 durometers, at least 80 durometers,at least 85 durometers, at least 90 durometers, at least 95 durometers,or 100 durometers; or midsole 148 material that is on a Shore D HardnessScale at least 20 durometers or at least 30 durometers or at least 40durometers or at least 50 durometers or at least 60 durometers or atleast 70 durometers or at least 80 durometers or at least 90 durometers;or midsole material that is on the Asker C Hardness Scale greater than70 durometers or over 75 durometers or over 80 durometers or over 85durometers or over 90 durometers or over 95 durometers or 100durometers. Accordingly, for each of the embodiments disclosed in thisapplication, the midsole material 148 may be designed with thisincreased firmness/hardness as discussed in this paragraph above (forexample, a hardness of greater than 60 durometers).

The midsole 148 used in the applicant's footwear or orthotic inventionscan have multiple layers, each with different durometers (of eitherscale), such varying from a firmest nearest to an outsole and a leastfirm nearest to a wearer's foot sole.

Also, since the applicant's view outlined above is that the function ofmidsole 148 material is to provide flexibility, not to providecushioning, then the use of conventional foamed material is no longerrequired, given that the injection of gas to create cells withinconventional midsole 148 material as identified earlier is done toproduce an unnecessary cushioning property into the 148 material.Therefore, reduced foam or non-foamed plastic or other reduced foam ornon-foamed elastomeric (or non-elastomeric materials) or combinationthereof can be usefully employed with improved function in thefootwear/orthotic soles 28 and removable midsole/orthotic inserts 145 ofthis application or the applicant's prior footwear applications andpatents incorporated by reference herein above. Similarly, reduced cell(open or closed) or non-cell plastic or other reduced cell (open orclosed) or non-cell elastomeric (or reduced or non-elastomeric)materials or combination thereof can be usefully employed with improvedfunction in the footwear/orthotic soles 28 and removablemidsole/orthotic inserts 145 of this application or the applicant'sprior footwear applications and patents incorporated by reference hereinabove.

Note that the above reduced foam or non-foam and/or reduced cell ornon-cell elastomeric (or reduced or non-elastomeric) midsole 148material described in this paragraph can be otherwise the same as thoseremaining midsole 148 materials (but without foam and/or cells orreduced foam and/or reduced cells in terms of size or number) indicatedpreviously in paragraph 0178 of the '087 application. Associated withthis reduction would be a cessation or reduction in the gas injected inthe midsole 148 manufacturing or injection process. Note the reductionin cells above can be in number (per unit volume, for example) or sizeor both, and reduced foam and/or cells can be measured in increasedweight per unit such as volume of material, for example.

In summary, it is the use of the applicant's insertable internal sipeinventions, including the 510/511/513 inventions of this application,not midsole 148 foamed or cellular material, that can provide naturalflexibility and impact force reduction like the foot sole of the wearer.In combination with the applicant's novel insertable internal sipeinvention, this new to the footwear art midsole 148 material describedabove uniquely provides a new capability for footwear/orthotic soles 28to function in the same manner and with the same performancecharacteristics as a wearer's foot sole—an important capabilityunavailable with conventional foamed or celled midsole 148 material. Andthis beneficial new combination can also be combined usefully with anyof the applicant's prior footwear/orthotic sole 28 and removablemidsole/orthotic insert 145 to produce other new invention withimproved, more natural performance characteristics.

The bottom or outer sole 149 is often made, at least in one or moreparts, with blown rubber for cushioning and flexibility, so that it issimilar in structure and function to foamed, celled midsole 148 materialdescribed previously. For the same reasons described previously then,the use of non-blown rubber (or reduced cell/foam rubber) combined withthe applicant's internal sipe inventions, such as the 510/511/513inventions of this application, provide useful improvements tofootwear/orthotics 28 and removable midsole/orthotic inserts 145, andcan also usefully be employed in conjunction with the reduced foam ornon-foam and/or reduced cell or non-cell midsole 148 material describedin the previous paragraph.

For both reduced foam or non-foam and/or reduced cell or non-cellmidsole 148 or bottom sole 149 materials, the new materials share thenew property of less or no substantial reduction in thickness undercompression from a body weight load of a wearer, while rigidity isavoidable through the flexibility provided by the applicant's internalsipes inventions, including the 510/511/513 inventions of thisapplication. Incompressible solids, that is, materials that can bedeformed but do not change in volume are described by the Mooney-Rivlenequation, which can be useful in identifying material properties withoptimal material characteristics desired by the applicant, which isminimal thickness reduction under compression, but with maximalflexibility.

The additional use of fiber, including inelastic but flexible fiber, isbeneficial in assisting the new midsole 148 (or bottom sole 149) toreduce compression deformation while maintain flexibility of thefootwear/orthotic 28 or insert 145, especially if the fiber 518 islocated or oriented substantially in a plane at least roughlyparalleling the inner surface of the sole 28 or insert 145 which shouldfollow the outer surface of the wearer's foot sole.

The firm or hard material described above for midsole 148 and bottomsole 149 provides better responsiveness than softer materials, adesirable characteristic for athletic shoes particularly and generallybetter stability for any footwear/orthotic soles 28 or inserts 145.Similarly, reduced foam or non-foam and/or reduced cell or non-cell sole148 or 149 material allows for thinner footwear/orthotic soles 28 orinserts 145, which reduces the torque inherent in the thickness of thesole 28 or insert 145, thereby also increasing responsiveness anddecreasing instability, such as related to ankle sprains orover-pronation.

Moreover, the applicant's 510/511/513 are uniquely designed to reduceshear forces, rather than compression force (which as noted above isprobably unnecessary), since most artificial surfaces like concrete orasphalt significantly increase shear forces above a natural level,compared to a natural surface like grass or dirt (either loose orpacked). In addition, the potentially excessive bulkiness of theapplicant's curved stability sides shown in this and earlierapplications and patents incorporated by reference herein above isreduced by the thinner sole 28 or insert 145.

Potential midsole 148 and outsole 149 materials include elastomers,rubber, and plastic, as noted above, including polymers (used singularlyor in combination); examples are polyolefins, fluoropolymers, andvinyls, as well as polypropylene, polystyrene, nylon, polycarbonate andacrylics, including in the form of fibers. Also, materials with aflexural modulus higher or much higher than is standard in the art isbeneficial.

The new firm or hard, reduced foam or non-foam and/or reduced cell ornon-cell 148 or 149 materials described above on this and the previousthree pages can be used beneficially with footwear/orthotic soles 28 anduppers 21, as well as removable midsole/orthotic inserts 145, and alsowith any other of the previously or later describednon-footwear/orthotic products, including, for example, helmets 550,balls 530, tires 535, implants or external pads or other protection 540,structural elements 550 including golf clubs 550, artificial joints likespinal disks 560, and many other products described or listed in this orprevious applications and patents previously incorporated by referenceherein.

The same logic described above that indicates the improvements providedby using firm-to-hard, reduced foam or non-foam and/or reduced cell ornon-cell 148 or 149 material also applies to materials used in theapplicant's internal sipe inventions, including the 510/511/513inventions of this application, including for example midsole materialused in either the 504 or the 502 components (or both) of the sipedcompartment 510 and 511 inventions.

By the same logic, any gas or “air” used in the 510/511/513 or earlierinventions is less beneficial, although still a useful improvement tothe prior art. Furthermore, by this logic, eithercompartment/chamber/bladder 500 or 501 can contain a firm-to-hard,reduced foam or non-foam and/or reduced cell or non-cell midsole 148material, either in a single layer or multiple layers separated byinternal sipes 505 (one or more) between layers, for example a singlesipe 505 between two midsole 148 material layers, such as in the exampleembodiment shown in FIG. 45, wherein the inner compartment 501 containstwo midsole layers. Any practical number of midsole layers of any shapeand associated sipes 505 of any shape is possible, with each additionalassociated sipe 505 providing additional flexibility to thecompartment/chamber/bladder 500 or 501.

FIG. 46 shows a different example embodiment wherein the innercompartment/chamber/bladder 501 shown contains a multitude of ballbearing-type structures made of a midsole 148 material that isfirm-to-hard, reduced foam or non-foam and/or reduced cell or non-cell,as described above. The ball bearings 516 can be fixed or free-movingwithin the inner compartment 501, so that for example if the ballbearings 516 are sufficiently firm-to-hard, the bearings 516 can createsignificant pressure points against a wearer's foot sole since thebearings 516 would not compress significantly under a wearer's bodyweight load, but if relatively free-moving within compartment 501 (oralternatively, with compartment/chamber/bladder 500, such as free-movingwithin a sipe 505, for example), the ball bearing 516 pressure pointscan move sufficiently within the compartment/chamber/bladder 501 toprovide thereby a foot massage to a wearer of the footwear/orthotic sole28 or removable midsole or orthotic insert 145 with acompartment/chamber/bladder 501 or sipe 505 with sufficientlyfirm-to-hard ball bearings 516, which also assist in developing healthyprotective calluses (rather than potentially blisters if the ballbearings 516 were fixed in the same positions so that the point pressuredid not move, such as randomly, which protects the foot sole)

FIG. 47 shows an embodiment example wherein flexible fiber is used toreinforce one or more compartment/chamber/bladders 500 or 501, as shown,wherein elastic or inelastic fibers 518 can be used to help stabilizethe size and shape of the one or more compartments/chambers/bladders 500or 501, such as for example under a body weight load of a wearer, toreduce compression of the sole. Note the fiber 518 shown parallel theshape of the inner surface 30 of the footwear/orthotic sole 28, whichparallels the shape of a wearer's foot sole.

FIG. 48A shows another example embodiment with fiber 518 wherein thefiber 518 is sandwiched between two separate layers of midsole 148 (orbottom sole 149) material, including firm-to-hard, reduced foam ornon-foam and/or reduced cell or non-cell; alternatively, the fiber 518can be embedded within the midsole 148, as shown in FIG. 48B, or bottomsole 149 material; multiple layers of fiber and/or midsole 148 can be auseful improvement, again as shown in FIG. 48B.

The benefit of this material structure is that the liquidor gel cell would be at least minimal compression under a body weightload, in marked contrast to the substantial compression and associateddegraded performance of conventional midsole 148 materials withconvention gas cells. Liquid or gel injection molding can be utilizedtherefore in place of gas injection molding.

FIG. 80A shows that, in an analogous way, especially to the thicker heelportion of a typical shoe sole, a thick urban area telephone book has ineffect hundreds of mostly “internal sipes”, each page being in effectseparated by a horizontal internal slit from each adjacent page, each ofwhich thereby is able to move freely relative to each other, resultingin a flexible telephone book that bends quite easily as is well known byall, while at the same time relatively stable when a vertical force likebody weight is applied. FIG. 80B shows, in contrast, if the same woodfiber material with the same dimensions as a thick telephone book wereformed instead into a single piece of wood with no pages, like a solidparticle board, it would be quite rigid with little flexibility,although it will support a body weight stably. FIG. 80C shows if,instead, the sipes were rotated 90 degrees into vertical slits and opento the bottom, so that the spine of a much wider telephone book withshorter pages is on top (in the form of a shoe sole with deep openexternal sipes, those external sipes would also provide a substantialamount of flexibility like that of the human foot sole, but at the costof excessive instability when a vertical force like body weight isapplied, as is obvious from common experience, since the pages willsplay out uncontrollably.

FIGS. 81A-81D shows the a significant benefit of the applicant'sinsertable sipe component 510/511/513 compared to the applicant'searlier sipe invention, which is shown in FIG. 81A (which is FIG. 12B ofthe '665 application), wherein sipes are indicated by numerals 181 and182, which allows an inner midsole section 188 to move freely insideouter midsole sections 184 and a bottom sole 149. The sipes are createdby not gluing the three sections together during assembly of the shoesole except where the outer midsole sections 184 join the bottom sole149 at numeral 8. FIG. 81B highlights the very small area of the gluejoint, which requires a delicate and new manufacturing glue step ofgreat accuracy during assembly and a resulting relatively weak jointbetween bottom sole and midsole, for example.

FIG. 81C shows an example of the applicant's 510 invention thatillustrates the much larger glue joint between midsole and bottomsolesurfaces allowed through the use of the outer chamber 500 component, allof which can be glued to the surrounding midsole and bottomsole in aconventional assembly fashion, so that manufacturing of a shoe sole withthe 510 invention is much simpler and unchanged from normal currentpractice for assembling conventional shoe soles with gas bladders likeNike Air™ and the resulting bond between bottomsole and midsole is muchmore secure, similar to that of a conventional shoe sole. FIG. 81D showsthe very much larger surface area 8 used for gluing the bottom sole 149to the outer midsole 184 (compared to the small glue area 8 shown inFIG. 81B and resulting much weaker joint between sole components in theearlier FIG. 81A sipe invention than in conventional shoe soles).

FIGS. 82A-87 illustrate further embodiments of the use of internallysiped compartments or chambers (510) and/or flexible inserts andinternal sipe components (511 and 513) with different shoe sole ororthotic configurations. FIG. 82A-82C, 83A-83C, 84A-84F, 85A-85D,86A-86E and 87 are example embodiments of the 510 or 511 or 513inventions in the embodiments shown in FIG. 11A-11C, 21-23, 39A-39E &40, 49A-49D, 51A-51E, and 62 of U.S. application Ser. No. 11/282,665,filed Nov. 21, 2005 and published on Nov. 9, 2006, on Pub. No. US2006/0248749 A1, which is incorporated by reference in this application.

The many preceding examples of embodiments of the applicant'sinventions, devices or flexible inserts or components 510, 511, and 513,have many useful applications. Generally, the resilient inserts 510,511, and 513 can be used for cushioning an object or a user, includingcushioning equipment and apparel for athletic or non-athletic,occupational, recreational, medical, and other uses, including afootwear sole or upper or orthotic or orthotic upper, as well asover-the-counter footwear inserts, such as pads, insoles or archsupports.

The flexible inserts or components 510, 511, and 513 can be used in anyprotective clothing, like flexible insert 510 in the interior of thehelmet shown in FIG. 24 that can be employed for any typical helmetapplications, examples including sports like American football, biking,climbing or hockey and others; occupational, like construction ormilitary or others; and transportation, like motorcycle, bicycle,automobile, or other; the flexible insert 510 (or 511 or 513 as usefulalternatives) is shown as padding inside a relatively hard or semi-hardouter shell protective material including materials like plastic,carbon-fiber, ceramic, or other composites or metal or combinationsthereof. The flexible inserts 510, 511, and 513 can be used in a similarshell construction for athletic or military protective equipment likeface masks (which can be attached or integrated into the helmet), neck,shoulder, chest, hip, knee or elbow, shin and forearm guards, thigh orbiceps guards, groin, hand, foot, and other guards, pads, or protectors.

Alternatively, flexible inserts or components 510, 511, and 513 can beused as padding alone or with a soft or relatively soft outer surface(without a hard shell) for medical uses (prescriptive or over thecounter) like generally in the field of orthopaedics (like braces, suchas back or leg or ankle braces and replacement spinal or other disks forspinal or other joint surgery or non-joint surgery), plastic surgery(including breast and other fatty deposit replacement/enhancementimplants), prosthetics and podiatrics, and elderly or recuperative careto protect the above noted anatomical structures and for dentalapplications, like mouth guards (athletic teeth protectors and nightguards and braces); in addition, similar padding can be used onartificial limbs and other prosthetic devices or braces and handles orgrips, such as for crutches, walkers, canes; or in sports rackets ortools, like hammers, including powered, and handlebars, and guns andrifles and other devices with recoil shock; or for safety padding forcrash protection, such padding for automobile dashboards or seat backs(including in airplanes, buses, and crash safety inflatable air bags.

Broadly, the flexible inserts or components 510, 511, and 513 can beusefully employed anywhere that cushioning already is being used,including bed and other furniture cushioning (including for specialseating needs, like bicycle or other seats), packaging for shipping,luggage, playground and other flooring, protective padding or cases forequipment of any sort, including portable devices like PC laptops orvideo players and/or games, cell phones, personal digital assistants(PDA's), and personal digital music players like Apple Ipods™ and MP3players, as examples, such as the mounting of delicate electronic (orother) components like hard-drives or for vibration dampening, such asin automobile structural and body components and connections.

No. 7,010,869, issuedMar. 14, 2006 (of which the '034 application is a continuation). Both ofthose '087 and '034 Applications and their U.S. publications and the'869 patent are hereby expressly incorporated by reference in itsentirety for completeness of disclosure of the applicant's combinationof one or more features or components of those prior published FIGS.1-75 with one or more features or components of FIGS. 1-23 and 25-26 ofthe present application, as described in the preceding paragraph.

In addition, one or more features or components of FIGS. 1-23 and 25-26of the present application can be usefully combined with one or morefeatures or components of FIGS. 1-43 of the applicant's earlierapplication Ser. No. 11/179,887 published as Publication No. US2005/0241183 A1 on Nov. 3, 2005 describing footwear. The '887 is herebyexpressly incorporated by reference in its entirety for completeness ofdisclosure of such novel combinations of any part or parts of thisapplication, including any one or more features or components of newFIGS. 1-23 and 25-26 described in this application, and any one or morefeatures or components of prior FIGS. 1-43 from any part or parts of the'887 application (and/or additionally combined with any part or parts ofthe preceding '087 and/or '034 applications or the '665 application).More explicitly, any one or more features or components of new FIGS.1-23 and 25-26 described in this application can be usefully combinedwith any one or more features or components of '887 FIGS. 5-7 withuppers that envelope the midsole and/or outsole and/or other featuresshown; '887 FIGS. 9-10, 12E, 12F, 13E, and 14A with anthropomorphicshapes and/or chambers and/or other features shown; '887 FIGS. 11,12A-12D and 13A-D with footwear soles incorporating fibers and/or otherfeatures shown; '887 FIGS. 16A-D through 27 with footwear sole internalsipes and/or other features shown; '887 FIGS. 28-30 with sufficientwidth in the form of rounded sides to support neutrally the full rangeof a wearer's ankle and foot motion and/or other features shown; '887FIGS. 31 and 32A-32M with footwear sole support, including for women'shigh heel pumps, at one or more of the applicant's essential stabilityelements and/or other features shown; '887 FIGS. 35-40 with footwearsole sipes in the form of slits and channels and/or other featuresshown; '887 FIGS. 41-42 with footwear soles having uniform frontal planethickness (measured in a frontal plane cross-section) and naturalflattening deformation under a wearer's body weight and/or othersfeatures shown; and '887 FIG. 43 with footwear soles having roundedsides with higher density midsole sides and/or other features shown.

Any combination that is not explicitly described above is implicit inthe overall invention of this application and, consequently, any part ofthe inventions shown in the examples shown in preceding FIGS. 1-79and/or textual specification can be combined with any other part of anyone or more other inventions shown in FIGS. 1-79 and/or associatedtextual specifications and also can be combined with any one or moreother inventive examples of published '665 application prior FIGS. 1-82and/or textual specification of this application to make new and usefulimprovements over the existing art.

Published '665 Application prior FIGS. 1-82 and associated textualspecification are also the same—verbatim—as the applicant's PCTapplication No. PCT/US01/13096, published by WIPO as WO 01/80678 A2 on 1Nov. 2001; for completeness of disclosure, WO 01/80678 A2 in itsentirety is also herein incorporated by reference into this application,as is PCT/US01/23865, published by WIPO as WO 02/09547 A2 on Feb. 7,2002, both of which are available to the public in English on the WIPOWeb Site in their entirety. Also incorporated by reference herein ispublished PCT Application No. PCT/US2005/042341, which is the same inits entirety as the '665 Application.

The '547 WIPO publication, titled “Shoe Sole Orthotic Structures andComputer Controlled Compartments”, is also incorporated herein byreference to provide additional information on the applicant's priororthotic inventions, which can usefully be combined with the orthoticinventions described and claimed in this application. However, theapplicant's insertable midsole orthotic 145 in the '547 Publication (andthe above referenced '034 application on orthotics) is very similar tothe applicant's removable midsole insert 145 as described in thisapplication and can generally be understood to be the same in structureand materials, although with a principal difference. Typically, anorthotic 145 is designed specifically for an individual wearer, unlikealmost all footwear, which is mass-produced using lasts based on averagefoot shapes for specific populations; the only exception is customfootwear, which is relatively rare and simply cobbled more directly tothe individual shape of the wearer's feet. The principal difference isthat typically orthotics 145 are designed to be prescribed, for example,by a qualified expert like a health care professional such as a doctoror podiatrist in order to treat a wearer's diagnosed footwear-relatedproblem; generally, orthotics 145 are for prescriptive, therapeutic,corrective, or prosthetic uses.
